I'm considering a project. I'd like to toss up a light with a solid state relay on it which would only turn on when I'm recording in Cubase. On playback the light would be off. I'm fairly imfamous for announcing "LISTENING" just before we do the playback, but a lot of time is wasted when a light could take care of all of it.

I'm guessing the heavy lifting would be more on the software end as I've done light relays before.

Anyone have any guesses as to where to start. I'm not even sure this would even require the Arduino now that I think about it.

I don't think so... You can't re-program Cubase. (But, I don't own Cubase.)

You could build a MIDI-controlled relay/light, but you'd have to click a button to send the MIDI command before recording. If you have to click something to turn on the light, that's a lot more trouble to build & set-up than simply wiring-up up a regular 'ol light switch.

Unless... Maybe there is a way to automate stuff in Cubase? For example, if can you set-it up some sort of batch operation in Cubase where you click on a command and have it start recording and send-out a MIDI command to a MIDI instrument. There is a MIDI Shield that allows the Arduino to send/receive MIDI commands.

I think you need to use MMC? Midi machine code. This sends out a message for start,stop,ff,rr and song position. I think you can set cubase to have a bar or two intro so the play/record light comes on early but still when you press play/record. You could display all the transport info on some kind of led display maybe.

I just finished an 8ch version last week, but as is I'm not aware of how to use if to for this case.

The use of a switch for this is a non-option. My sessions are WAY too fast and even though I've probably logged 10,000 hours on Cubase I can keep up with few clients. My console, compressors, etc keep me VERY busy at work. I'm looking for an automated solution.

Hmm! Now that sounds very, very interesting. Thanks! I'll look into it. If that does what I want I simply need a solid state relay. This project will be a breeze. (Famous last works. )
